SEGTIONAL TROUGH.

Specification of Letters Patent.

Patented Sept. 15, 1914.

Application filed. January 22, 1912. Serial No. 672,730.

To all whom it may concern:

Be it known that I, FnANoIs W. CARPEN- run, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Sectional Troughs, of which the following is aspecification.

lady invention relates to improvements in troughs designed particularly to form a part of a wing carrier to be used in connection with the feeder of a threshing machine, and consists in an improved construction of foldable trough.

To this end the invention consists in the features of construction, combination, and arrangement of parts hereinafter described and claimed.

In the accompanying drawings forming part of this specification, Figure 1 is a side elevation of my improved trough in eX- tended position; Fig. 2 is an end view of the same; Fig. 3 is a side elevation of the trough in folded position; Fig. 4 is a perspective view of a bearing bracket forming part of the invention; Fig. 5 is a perspective view, broken away, of a locking device for holding the trough in extended position; Fig. 6 is a perspective View, broken away, of one end of the trough; and Fig. 7 is. a side elevation of the trough in partly folded position.

In carrying out my invention the trough is constructed of a plurality of sections A, a trough made of two sections being shown in the drawings, connected at their upper meeting edges by hinges 2. 3 represents an endless carrier chain extending through the trough and formed with suitable carrying forks 4. At one end of the trough the chain runs over a sprocket 5, the shaft supporting said sprocket having suitable journal sup port 6 below the corresponding end of the trough. Ihe chain at the opposite end of the trough runs over a sprocket 7 the shaft of the sprocket 7 being journaled in a bearing 8. The bearing 8 is formed withoutwardly extending flanges 9 slidable'in the sides 10 of a bracket 11, the bracket 11 being suitably supported under the adjacent end of the trough. The bracket 8 is normally held pressed outward to hold the endless carrier chain taut by means of a coil spring 12 surrounding the rod 13, said rod being shownsecured at one end in the bearing 8' spring may be adjusted. When the trough is folded, as shown in Fig. 3, the loose inner portion of the carrier chain will stand in side the alining hollow centers of the trough sections, the loose portion of the carrier chain being held by means of a spring and chain 17 connected with the inner end of one of the sections in position to be hooked over the carrier chain. 7

In order to hold the trough sections locked in extended position I provide the locking device shown particularly in Fig. 5. This consists of a bracket 18 secured underneath the inner end of one of the trough sections, a shaft 19 being journaled in said bracket and supporting a lever 20 adapted to be held in looking position by a spring 21. A socket member 22 is secured underneath the inner end of the adjacent trough sec tion and formed with an opening 23 to receive the hooked end 2a of the locking member. l/Vhen the trough is turned into extended position the spring 21 will force the lever 20 into locking engagement with the opening 23. The locking lever may be manually turned against the tension of the spring 21 to release it from locking position when it is desired to fold the troughs. The sprocket 5 may be operatively connected with the actuating mechanism, not shown, through the medium of gears 26 and shaft 25.

In operation, when the trough is folded the chain supporting bracket 8 will slide,

as hereinbefore described, to prevent breaking of the carrying chain and as will be evident said sliding support always holds the chain taut and takes up any looseness caused by wear. When the trough is in extended position thechain 17 may be hooked underneath the trough sections as shown in Fig. l to be out of the way.

I claim as my invention:

A trough of the class described comprising a plurality of sections hinged together, an endless carrier extending through said trough and a sprlng tensloned chain secured to the inner end of one of the trough sec- In testimony whereof I afiix my signature tions and adapted to be hooked to said carin presence oi two Witnesses.
